Aplicação de gelatina obtida de subproduto animal como substituto parcial de gordura em spread de chocolate

O objetivo do presente estudo foi verificação da viabilidade da aplicação de gelatina de pés de frango em spread de chocolate como substituto parcial de gordura. Inicialmente apresentou-se uma revisão de literatura sobre os principais aspectos que envolvem a pesquisa. Após relatou-se a metodologia de extração e caracterização físico-química da gelatina obtida de pés de frango por meio de análises de composição centesimal, de cor, força de gel e análise de perfil de textura (TPA). Posteriormente abordou-se os efeitos da aplicação de gelatina como substituto de gordura nas propriedades físico-químicas e reológicas de spread de chocolate. Por último investigou-se a influência da concentração de gelatina e substituição de gordura na espalhabilidade, estabilidade (shelf life), custos e propriedades sensoriais dos spreads de chocolate. Para tanto, foi utilizado planejamento experimental Central Composto Rotacional e metodologia de superfície de resposta. Os resultados da extração de gelatina de subproduto de frango indicaram que as peles e tendões dos pés de frango possuem rendimento (7,83 %) e conteúdo mineral (1,92 %), apresentando alto teor proteico (84,96 %) próximo das gelatinas comerciais. Em concentração de 6,67 % a gelatina demonstrou elevada força de gel (294,78 g), comportando-se na análise de perfil de textura como um sólido. Os dados relacionados às formulações de spread de chocolate demonstraram que tanto o nível de substituição de gordura quanto a concentração de gelatina exerceram efeitos significativos (p<0,05) sobre a cor, volume, densidade e comportamento reológico dos produtos, exceto a atividade de água que foi influenciada apenas pelo primeiro fator. Sob a perspectiva reológica apenas a amostra com maior nível de substituição de gordura foi classificada como pseudoplástica. A gelatina contribuiu no aumento do teor proteico das formulações. A consistência foi significativamente (p<0,05) influenciada pelas propriedades da fase de gelatina, apresentando ampla faixa de plasticidade nas diferentes temperaturas (10, 20 e 30 °C). A consistência dos spreads aumentou em todas as temperaturas durante os 90 dias de armazenamento. Observou-se por meio da análise sensorial que os fatores em estudo provocaram alterações nos atributos sensoriais do produto suficiente para a percepção dos provadores. A formulação com 75 % de substituição de gordura seguida pelas formulações com 50 % e 0,8 % de concentração de gelatina apresentaram a maior aceitabilidade. Com o máximo de substituição de gordura chegou-se a 53 % de redução de custos. Contudo, os resultados obtidos sugerem que a aplicação de gelatina de pés de frango pode ser vantajosa, já que contribuiu com a formulação de spreads de chocolate menos calóricos e com propriedades físico-químicas e sensoriais adequadas para uma possível comercialização.

Remembering Liberal Feminism In Radical Ways: Locating Conservative Strategies In The Narratives Of Dr. Christina Hoff Sommers, Tammy Bruce, And Dr. Laura Schlessinger

This dissertation identifies and challenges post-feminist narratives that remember the second wave or 1960s and 1970s liberal feminism as a radical form of activism. The narratives of three prominent post-feminist authors: Dr. Christina Hoff Sommers, Tammy Bruce and Dr. Laura Schlessinger are used as examples of how identification works as a rhetorical device that motivates individual actors to join in a struggle against liberal and radical feminist ideologies. I argue that each author draws on classically liberal and politically conservative virtues to define a "true" feminism that is at odds with alternative feminist commitments. I demonstrate how these authors create a subject position of a "true feminist" that is reminiscent of the classically liberal suffragist. In Burkean terms, each author constitutes the suffragist as a friend and juxtaposes her with the enemy--modern liberal and radical feminists. I articulate the consequences of such dialectical portrayals of feminist activism and further suggest that these authors' visions of feminism reinforce patriarchal practices, urging women to assimilate into a classically liberal society at the cost of social justice. In opposition to their memories of feminism, I offer a radical democratic approach of remembering feminism that is less concerned with the definition of feminism or feminist than it is with holistically addressing oppression and what oppression means to subjugated populations.

Constructing a Neuroscientific Pastoral Theology of Fear and Hope

Contemporary therapeutic circles utilize the concept of anxiety to describe a variety of disorders. Emotional reductionism is a detriment to the therapeutic community and the persons seeking its help. This dissertation proposes that attention to the emotion of fear clarifies our categorization of particular disorders and challenges emotional reductionism. I propose that the emotion of fear, through its theological relationship to hope, is useful in therapeutic practice for persons who experience trauma and PTSD. I explore the differences between fear and anxiety by deconstructing anxiety. Through this process, I develop four categories which help the emotion of fear stand independent of anxiety in therapy. Temporality, behaviors, antidote and objects are categories which distinguish fear from anxiety. Together, they provide the impetus to explore the emotion of fear. Understanding the emotion of fear requires an examination of its neurophysiological embodiment. This includes the brain structures responsible for fear production, its defensive behaviors and the evolutionary retention of fear. Dual inheritance evolutionary theory posits that we evolved physically and culturally, helping us understand the inescapability of fear and the unique threats humans fear. The threats humans react to develop through subjective interpretations of experience. Sometimes threats, through their presence in our memories and imaginations, inhibit a person's ability to live out a preferred identity and experience hope. Understanding fear as embodied and subjective is important. Process theology provides a religious framework through which fear can be interpreted. In this framework, fear is developed as an adaptive human response. Moreover, fear is useful to the divine-human relationship, revealing an undercurrent of hope. In the context of the divine-human relationship fear is understood as an initial aim which protects a person from a threat, but also preserves them for novel future relationships. Utilizing a "double-listening" stance, a therapist hears the traumatic narrative and counternarratives of resistance and resilience. These counternarratives express an orientation towards hopeful futures wherein persons thrive through living out a preferred identity. A therapeutic practice incorporating the emotion of fear will utilize the themes of survival, coping and thriving to enable persons to place their traumatic narrative within their meaning systems.

Sense-Making Bodies: Feminist Materiality and Phenomenology in Constructive Body Theologies

Constructive body theology provides an ethical commitment to and a set of analytical principles for understanding bodily experience. If we insist upon the theological value of embodied experience, how can we give an adequate account of it? Are feminist appeals to the senses useful in developing theological truth claims based in embodied experiences? Feminist theologies which explicitly seek to overcome body/mind dualisms often reinscribe them when they neglect to attend to perception as a critical element of bodily experience. Phenomenological analyses of perception (such as suggested by Merleau-Ponty) strengthen and refine our conception of embodiment. Grounding constructive theology in experience requires understanding experience as bodily perceptual orientation, as perceptual bodily and cultural acts involved in socially and historically situated contextual meaning-making processes. This shift expands phenomenological concepts such as intentionality and habit, and allows for a comparative investigation of historical and cultural differences in embodied experiences through examples found in sensory anthropology. Body theology, framed as principles, strengthens theological projects (such as those by Carter Heyward and Marcella Althaus-Reid, as well as new constructive possibilities) through opening dialogical avenues of exploration into embodied being in the world. Body theology principles help us conceive of and address how our bodily experiencing--our feeling, tasting, hearing, imaging, remembering and other sensory knowledge --comes to matter in our lives, especially where oppressive forces viscerally affect embodied life.

Discreta regente, la austriaca o Doña Virtudes. Las imágenes de María Cristina de Habsburgo

Más allá del mito de la discreta regente de España, María Cristina de Habsburgo ofrece una imagen poliédrica que puede contribuir a calibrar la importancia política, cultural y social de la representación simbólica de la corona. Las imágenes —oficial, de la oposición y populares— de María Cristina son analizadas desde diversas perspectivas: la consolidación de una monarquía en crisis tras el fallecimiento de Alfonso XII pocos años después de la República, la creación de una identidad nacional todavía no afirmada y la conformación de los estereotipos de género en torno al discurso de la separación de esferas. Imágenes que daban respuestas muchas veces divergentes a las circunstancias que distinguían a Maria Cristina de otros monarcas: era regente y no reina por derecho propio, era extranjera pero ocupaba el trono español y era mujer pero desempeñaba la más alta magistratura del país.

The relevance of harmonising the technical level of social housing with the urban level of the neighbourhood through the example of the 500 dwellings in Albacete

The Architecture and Household Trade Union built nearly 2,000 subsidized dwellings in Albacete from 1941 to 1971. It was the responsible entity from the end of the Civil War until the beginning of Democracy of the social policy programs in Spain. Later on, and together with the National Housing Institute, were responsible for the construction activity. Its limited budget, scarcity of technical and human resources and an urgent need for new housing developments, constituted the basis for producing a vast housing market of low construction qualities. However, thanks to the true architectonic expertise of some of the professionals, some of the developments were designed with a clear urban strategy and in direct relation with the city, which characterizes them to be studied and conserved. This is the case for the selected development for the analysis, the urban complex of the 500 dwellings in Albacete, the Hermanos Falcó Neighborhood. Designed and built between 1963, Alfonso Crespo and Adolfo Gil architects, and 1977 second reformed project by the architect Fernando Rodríguez. It is characterized by its layout on the territory, its controlled relation with the city and its different types of open blocks. Above all, its spatial and human scale strengths, directly related to the European post-war proposals, have to be emphasized; although its technical deficiencies affect the interior quality of the houses. This paper examines its virtues and failures and proposes, using current tools, its renovation. This proposal main aims are to extend its lifetime and develop the particular and urban sustainability levels.
